Application filed. Iltarch 29, 1915. I Serial No. 17,790.

To all whom it may concern:

7 Be it known that I, JOHN C. TATE, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Heaters, of whichthe following is a specification.

The present invention relates to improvements in heaters and moreparticularlyto a type of heater commonly known as gas radiators.

The invention consists in providing a structure of the radiator typewith a reheating chamber on either side of the combustion chamber andwhich will superheat the already heated gases at a point adjacent thedischarge opening, and thus cause a continuous circulation of gases inthe heater.

The invention also consists in providing one or more relief valves inthe heat circulation chambers to compensate for any sudden expansion ofthe gases when the burner .is lighted.

' The invention has for its objects to provide a heater of the abovetype having a large area of radiation surface, one wherein the heatedair and products of combustion are discharged into a chimney instead ofthe room in which the heater is located, one having a clear aircirculation, thus insuring proper combustion, and one provided withrelief valves which admit an escape of sudden undue pressures within theheater.

With the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claims hereto appended; it being understood that various changes inthe form, proportion, size, and minor details of construction withinthescope of the claims may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

To more fully comprehend reference is .directed to the accompanyingdrawings, wherein- Figure 1 is a view in side elevation of a radiatorconstructed 1n accordance w1th this invention. Fig. 2 is a verticalsectional view of the same. Fig. 3 is a view in end elevation ofa-portion of one of the sections, disclosing the reheating chamber.

closing the combustion chamber. Fig; 5 is a transverse sectional viewtaken on line 5-5 of Fig. 4. Fig. 6 is an enlarged detail of one of therelief valves in the upper portion of the heater in open position. Fig,7 to is a vertical sectional view of the valve in Fig. 6. Fig. 8 is atransverse sectional view: taken on line 88 of Fig. 7. Fig. 9 is a topplan view of one of the relief valves at the lower portion of theheater. Fig. 10 is a as front elevation of the valve disclosed in Fig.9, partly broken away. Fig. 11 is a vertical sectional view of the valvedisclosed in Figs. 9 and 10.

Referring more particularly to the several 7o views of the drawings,wherein like characters of reference refer to corresponding parts1designates a tubular radiator men1- ber preferably formed-verticallyinto two parts, the meeting edges of which are- 4 into which extends,through a suitable opening 5 a burner 6 connected to any suitable sourceof fuel supply. The burner is received at its inner end in a seat 7 andthe fuel fiow is controlled by a suitable valve 8.

A lighting aperture 9 is formed in the wall of the member 1 above theburner, and an open portion 10 is formed in the base to admit a1r forcombustion and for circulation through the radiator.

A reheating chamber 11 is formed on either side of the combustionchamber by the walls 12 which are preferably formed integral withthe'walls of the member 1 and extend approximately one-half of thelength of the'member 1. The chambers 11 connect as at a point adjacenttheir upper ends and provide an outlet 13 which is surrounded by aflange 16 projecting from the body 1, and to which a suitable stack isadapted to be attached.

the mom or 1 are formed with flanged outlet'openings 17, and the lowerportion of the walls 12 are each formed with suitable inlet openings 18,and communicating with the 105 respective openings are the flanged walls19 surrounding openings 19 in the upper and The '-u per ends of the sidewalls forming It will be apparent that the air entering the open portionlO and being heated by the flame from the burner will rise in thecombustion chamber 4 and pass with the products of combustion outwardlythrough the openings 17 into the tubular circulating sections 20 throughthe upper openings 19. The heated gases rising in the combustion chamber1 will cause the gases in the circulating sections 20 to pass downwardlyand into the reheating chambers 11 through the openings 18, thereheating of the heated gases causing a rapid circulation of gaseswithin the combustion chamber 1 and tubes 20, and the heated gases afterpassing through the reheating chamberswill pass outwardly through thestack opening 16.

It will be apparent that the heated gases passing into the reheatingchambers and being again heated therein, and to a higher temperaturethan that in the tubes 20,- will in passing through the stack opening 13draw the gases contained in the circulating sections 20 downwardly andthus maintain a constant circulation of heated gases within the heater.

The outer wall 21 of the circulation tubes 20 adjacent the openings 17and 19 are provided with suitable relief openings 22 at the upper endsand openings 23 at the lower ends, and through said openings are adaptedto pass any sudden excess pressures created within the heater, such asthat caused by the explosion of unconsumed gases in the combustionchamber. The openings 22, Figs. 6, 7 and 8, are normally closed bysuitable covers or valves 24: which are adapted to seat against theouter surface of an annular member 25 surrounding the openings. Securedto a lug 26 projecting from the inner face of each valve 24 is the shankportion 27 of a substantially T-shaped member 28, the weight of which issufficient to retain the valves in their closed position against theirrespective seats 25, and the lateral arms 29 of which contact with theinterior of the circulating tubes 20 and limit the outward movement ofthe valves.

Surrounding the openings 23-Figs. 9, 10 and 11, are annular flangemembers 30 against which abut the seats 31 for the cover plates orvalves 32 which are pivoted at their upper ends, as at 33, to the seats31 and are. normally closed by gravity. The seats 31 are formed with aweb 34 through which extends the rod 35 carrying the nuts 35 whichretain the flanges 19 of the lower opening 19 in contact with the wall12 surrounding the openings 18. Suitable yokes 36 connected by a rod 36'contactwith the inner surface of the walls 21 surrounding the upperopenings 19 in the circulating tubes 20 and retain the flanged walls 19thereof in contact with the wall surrounding the openings 17. Suitablesupporting legs 37 are-carried by the lower ends of the circulatingtubes 20 and support the heater above the floor.
